F期和D期混合通胀情景的严格约束

Tight constraints on F- and D-term hybrid inflation scenarios

Richard Battye, Bjorn Garbrecht, Adam Moss

摘要:

我们使用目前的宇宙学数据从宇宙微波背景,大尺度结构和氘在高红移约束超对称的F-和D-长期混合暴胀的情况下,包括可能的贡献的CMB各向异性宇宙弦。使用两种不同的实现的宇宙弦谱,我们发现,最小版本的D项模型被排除在高的意义。F项模型也与数据存在矛盾。我们还讨论了模型的可能的非最小变量。

英文摘要:

We use present cosmological data from the cosmic microwave background, large-scale structure and deuterium at high redshifts to constrain supersymmetric F- and D-term hybrid inflation scenarios including possible contributions to the CMB anisotropies from cosmic strings. Using two different realizations of the cosmic string spectrum, we find that the minimal version of the D-term model is ruled out at high significance. F-term models are also in tension with the data. We also discuss possible non-minimal variants of the models.
